These Welding machines functions both as Tungsten Inert Gas
(TIG) welding and MMA (Manual Metal Arc) Machine.
Touching live electrical parts can cause fatal shocks or
severe burns. The electrode and work circuit is
electrically live whenever the output is on. Incorrectly
installed or improperly grounded equipment is a hazard.
▪Insulate yourself from work and ground using dry insulating
mats or covers, big enough to prevent any physical contact with
the work or ground.
▪Do not connect more than one electrode or work cable to any
single weld output terminal.
▪Always verify the supply ground –check and be sure that input
power cord-ground wire is properly connected to ground terminal
in disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
Welding produces fumes and gases. Breathing these fumes
and gases can be hazardous to your health. Keep your head
out of the fumes. Do not breathe the fumes.
▪Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the
weld area, the area is well ventilated, and if necessary, while
wearing an air-supplied respirator.

Arc rays from the welding process produce intense visible
and invisible (ultraviolet and infrared) rays that can burn
eyes and skin. Sparks fly off from the weld.
▪Wear a welding helmet fitted with a proper shade of filter to
protect your face and eyes when welding or watching.
▪Wear approved safety glasses with side shields under your helmet.
Accidental contact of electrode to metal objects can
cause sparks, explosion, overheating, or fire.
Hot parts can cause severe burns. Do not touch hot parts
bare handed. Allow cooling period before working on gun
or torch.
Overuse can cause overheating; Allow cooling period
and follow rated duty cycle. Reduce the current before
starting to weld again. Do not block or filter airflow.
Moving parts can cause injury. Keep away from moving
parts such as fans. Keep all doors, panels, covers, and
guards closed and securely in place.
High-frequency due to welding can cause interference,
it can interfere with radio navigation, safety services,
sensors computers, and communications equipment.
Electo-static discharge can damage printed circuit
boards. Put on grounded wrist strap before handling
boards or parts.

Cylinders can explode if damaged; Shielding gas
cylinders contain gas under high pressure and damaged
cylinder can explode, so be sure to treat them carefully.
▪Keep cylinders away from any welding or other electrical circuits.
Never hang a welding torch over a gas cylinder.
▪Never allow a welding electrode to touch any cylinder. Never weld
on a pressurized cylinder –explosion will result.
▪When working with cylinders or operating cylinder valves, ensure
that you wear appropriate protectives, boots, clothing, gloves and
safety glasses. When moving cylinders, ensure that the valve is not
accidentally opened in transit.
▪Before operating a cylinder valve: Ensure that the system you are
connecting the cylinder into is suitable for the gas and pressure
involved. Ensure that any accessories (such as hoses attached to
the cylinder valve, or the system being connected to) are securely
connected.
▪Do not, in any manner, come into physical contact with any part
of the welding current circuit, which includes:
i. Workpiece or any conductive material in contact with it.
ii. Ground clamp.
iii. Electrode or welding rod.
iv. Any metal parts on the electrode holder or TIG Torch.
▪All the equipment should be kept in good working condition,
inspected and, when defective, promptly repaired or withdrawn
from service.
▪Training should be sought out in the safe use of this
equipment, the processes and the emergencies.

T220-105 and T250-106 Welding machines function both as
Tungsten Inert Gas (TIG) and MMA (Manual Metal Arc) Machine.
▪In Tungsten Inert Gas (TIG) welding, a non-consumable
tungsten electrode is used to produce the weld. The weld area
and electrode are protected by an inert shielding gas (argon)
from oxidation or other atmospheric contamination. A filler
metal is normally used. A constant-current welding power
supply produces electrical energy, which is conducted across the
arc through a column of highly ionized gas and metal vapours.
TIG is most commonly used to weld thin sections of stainless
steel and non-ferrous metals such as aluminium, magnesium,
and copper alloys.
▪In Manual Metal Arc Welding (MMA), with consumable, flux-
covered electrode and a ground clamp, a short-circuit is initially
made on the weld piece. An electric arc forms between electrode
and work-piece, which heats up enough to melt both. As the
electrode melts, the flux coating on the electrode develops gas
and slag, which help protect the weld pool. The gas keeps air and
other pollutants away, while slag forms on top of the weld pool to
protect the weld seam.
▪The machine uses a high performance IGBT Technology, which
is very useful as they give power that can be used for different
welding processes.
Hot Start provides excellent arc ignition without the electrode
sticking and avoiding any metallurgical default in the weld. Its
Anti-sticking feature minimizes the short circuit current in the
event of the electrode sticking to the work piece.
VRD (Voltage Reduction Device) in-built function provides an
additional measure of safety.
Arc force in-built improves the weld performance on the specified
size of electrodes to be used, making the job easier.

The MMA/ TIG Switch (1) is used to switch between the two
welding operations: MMA and TIG welding.
▪Always fix earth cable clamp directly on the welding piece.
Turn the power switch to ‘ON’position. Cooling fan inside the
machine should begin to work once welding starts.
▪Clamp the welding rod on the electrode holder, the machine is in
the manual welding mode and in the standby state.
▪In accordance with the thickness of welding work-piece, diameter
of welding rod, working position and technology needs, make
sure suitable welding current with the adjustment knob (2).
(Check out the table on pg.no.11 for electrode size-current criteria)
(If current is too high, intensified splashing occurs and if low, the melted
welding stick becomes fluid and drop transfer would not proceed smoothly)
For beginners, the first difficulty is priming the arc.
For best results proceed as follows:
▪Test the current intensity and the electrode on a piece of scrap
material. Hold the electrode approx. 2 cm above the start of the
joint. Touch the work-piece with the electrode and stroke it
repeatedly on-off the work-piece to start the arc.
▪Watch the arc only through a face shield and keep the arc
length approximately 1–1.5 times the diameter of the electrode.
Hold the electrode at an angle approximately 70° –80°.
▪Wait until the joint has cooled completely before removing the
slag. If you wish to continue welding a joint after taking a break,
the slag at the end of the joint must be removed first. Prime the
arc in the joint and melt the electrode at the point where the two
joints meet.
GENERAL OPERATION
NOTE: It is recommended that you try welding and rate of welding
current first on something else than the actual work piece. You can
start welding after having made the necessary selections.

TIG welding works on same principle of arc welding. In a TIG
welding process, a high intense arc is produced between tungsten
electrode and work piece. A shielding gas (Argon) is also used which
protect the weld surface from oxidization.
▪Open the shielding cylinder and set the required gas flow using
the pressure (flow) adjustment knob on the regulator.
(Check out the table on pg.no.11 for gas adjustments)
▪Press the switch of TIG torch, electromagnetic valve is started.
Sound of HF arc striking can be heard, at the same time argon is
flowing from torch burner.
▪Set suitable welding current and make sure welding current is
adequate to thickness of work piece and process demand.
▪Maintain 2-4mm from tungsten electrode to work piece, press
switch of torch, burn and strike arc, sound of HF arc-striking will
be diminished. The welding machine can be operated now and the
operation can be conducted with the help of a filler rod.
TIG WELDING
NOTE: Before welding user must press switch of torch several seconds
until all of air is be drained out.
▪When welding is over, argon will still flow out in several seconds to
protect welding spot before cooed down. So, the torch must be kept
on welding place some time, before arc has been extinguished.

TIG WELDING FUSION TECHNIQUE:
Some welds combining thin materials can be accomplished
without filler metal like edge, corner, and butt joints. This is
known as Fusion welding, where the edges are melted together
using only the heat and arc force. Once the arc is started, the torch
is held in place until a weld pool is created, a circular movement of
the tungsten will assist in creating a weld pool. Once the pool is
established tilt the torch at about a 75° and move smoothly, evenly
along the joint while fusing the materials together.
75°
Weld pool
TIG WELDING WITH FILLER WIRE TECHNIQUE
A filler rod is added to the weld pool to build up reinforcement
and create a strong weld. The filler metal is introduced to the
leading edge of the weld pool formed by fusion. The rod is usually
held at 15°, the arc will melt the filler into the weld pool as the torch
is moved forward.
(Also, a dabbing technique can be used to control the amount of filler wire
added, the wire is fed into the molten pool and retracted in a repeating
sequence as the torch is moved slowly and evenly forward)
It is important during the welding to keep the molten end of the
filler wire inside the gas shield as this protects the end of the wire
from being oxidised and contaminating the weld pool.
